giving a sufficient Quantity of the Medicine
afterwards; as the Fits about this Period are wont to become
double, subintrant, or continual.--This did not always put an
immediate Stop to the Fever, but it invigorated the Powers of
the Body, and prevented or removed the dangerous Symptoms.
Having given the Bark on the fifth Day, if a Fit came on the
sixth, and declined the same Evening, he gave some more Doses
of the Bark to mitigate the Fit on the seventh; yet sometimes
this Fit of the sixth united with that of the seventh, and
the Patient had the Heat, Restlessness, Raving, and other
Complaints, greatly augmented, and the Case seemed more
desperate than ever; which, however, were more dangerous in
Appearance than Reality, and went off with a profuse Sweat
next Morning; after which he gave the Bark freely as before;
and this either stopt the Fits, or made them so moderate, as
that they yielded quickly to the same Sort of Management.--By
this Method, when Assistance is called timely, Mr. _Cleghorn_
says, the most formidable Intermitting and Remitting
Tertians, may be certainly and speedily brought to a happy
Conclusion about the End of the first Week, or Beginning of
the second. See _Observ. on the epidemic Diseases in
Minorca_, chap. iii. p. 187, &c.

In the Year 1761, we tried the Bark in various Forms in many Cases,
where the Patient had been blooded and purged in the Beginning, and
used the cooling Medicines; and where the Remissions were very clear:
Yet it had no Effect in removing the Disorder, except in two or three
Cases at _Munster_, where the Paroxysms assumed a tertian Form; for
the most part, it made the Patients more hot and feverish, and we were
obliged to leave off using it, as it was in Danger of changing the
remittent into a continued Fever. However, it was of Service after the
Fever came to a Crisis, and was going off; and Dr. _Pringle_ has very
justly observed, that it hastened the Recovery, and that those who
used it were less subject to Relapses than such as did not; and
therefore we commonly gave it in a convalescent State.--Before giving
the Bark, I always found it of Advantage to give a Dose of Rhubarb, or
of some other Purgative, or to mix some Rhubarb with the first Doses,
so as to procure the Patient some loose Stools.

When either the Fever went on without Intermission, or changed into a
continued Form, or th
